LT6656BIDC-3#TRPBF

Voltage Reference Overview

The LT6656BIDC-3#TRPBF is a precision series voltage reference manufactured by Analog Devices Inc. It provides a fixed output voltage of 3V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of 3.5V to 18V, drawing a typical supply current of 1µA. It features a minimum output drive current of 5mA and requires a minimum output capacitance of 1µF for stability. The component is housed in a 6-lead (2mm × 2mm) plastic DFN package and is specified for operation from –40°C to 85°C.

Voltage Reference Feature Summary

• Ultralow supply current consumption suitable for battery-powered applications

Voltage Reference Procurement Notes

Verify that the part number suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific grade 'B' designation aligns with the required 0.1% accuracy and 20ppm/°C drift specifications for your design. Ensure the DFN package dimensions match your PCB footprint constraints.

Voltage Reference Selection Notes

Select this component when a fixed 3V reference is needed with moderate precision requirements. The B-grade specification offers a balance between cost and performance compared to the higher-precision A-grade options. Consider the 20ppm/°C temperature coefficient against the thermal environment of the application to ensure long-term stability meets system tolerances.

Voltage Reference Part Context

This component belongs to the LT6656 family of micropower precision voltage references. The family includes various output voltage options and package types such as TSOT-23 and LS8. The BIDC variant specifically denotes the industrial temperature range, B-grade accuracy, and DFN packaging, distinguishing it from commercial grade or hermetic package alternatives within the same product line.
